3 Claims. (Cl. 229-33) Walter Patent No. 1,616,014,` dated February 1,'

One of the objects of the invention is to provide a collapsible box in which the ends are provided with slots or pockets and in which the top closure is provided with end extensions adapted to be readily and easily engaged in the slots or pockets to properly lock and hold the top closure in position.

Another object of the invention is to provide a knock-down box designed for packing relatively heavy materials which is readily and easily set up for use and which is capable of withstanding substantially the same loadsA as the non-collapsible tuck end container; l

Another object ofthe invention is toprovide a'collapsible or foldable paperboard containei which may be shipped or stored fiat when not in use. and which may be readily and easily opened to receive articles to be packed or may be folded to its collapsible position;

Another object of the invention is to provide a collapsible cardboard folding container which is simple and inexpensive to manufacture.`

Another object of the invention is to provide novel folding container and walls together with means for bracing the end walls when the container is in the set-up position whereby a strong y formed from the blank of Fig. 1 after being set up but with the closure panels still open;

Fig. 3 is a perspective view partly broken away illustrating the manner in which the container of Fig. 2 may be collapsed;` and tension panel i5 ls connected to the other side panel along score line I6.

'Il'he bottom wall panel I0 is connected to end walls or panels Illa` along score lines Il, and the k side walls II, Ii are likewise provided with end ilaps Ila, IIa connected thereto along score lines I8, f8. The cover panel I3 is provided with lateral extensions i3d, i3d hingedly connected to the cover panel along score lines 30. The end flaps Ila, and the ends of the sidewalls are separated from the end walls I0a by means of slots i9, I9.

In accordance with the present invention each of the end flaps l la are provided with a score line atively narrow portion 2l adjacent the side wall and thev wider portion 22 extending from the rig. 4 is a perspective view' showing the con;

tainer of Fig. 2 completely collapsed, for storage or shipping.v

In the drawingsreference numeral I0 denotes score line to the end of the flap. When the cartonis set up the narrow portions 2i of the end flaps are secured to the end walls in any suitable manner, as by staples 2l as indicated in Figs. 2 and 3. 'I'he end walls Illa are provided with diagonal score lines 23, which lines extend upwardly and inwardly at substantially 45 angles from the lower comers of the end walls.` 'These score lines provide foldable triangular shapedwing portions 24, 24 at the outer edges of the end walls ila. The extensions I3a, Ila of the'cover' panelv I3 have their outermost comers cut away at 25, 25 and also-haveportions 26, 26 cut from theiropposite freecorners, which cut away portions are at least as wide as the securing portions 2I oi' the end flaps lia. ,x

To set up the container, the side walls Il are ilrst folded upwardly o'n the score lines I2 and'v the end flaps IIa are folded inwardly about the score lines Il, after which the end walls Ina are folded upwardly and are secured to the narrow rectangular portions 2i ofthe end flaps Ila by stapling or otherwise. This leaves the relatively wider. portions 22 of the end flaps free to be grasped by the hands of the operator when it is desired to collapse or set up the carton. It will be noted that a portion of the end iiaps lia extend upwardly beyond the upper limit of the end walls Vor panels Ina, thereby rendering the upper part of portions 22 readily accessible. To collapse the container the portions 22 are pulled inwardly as indicated in Fig. 3, thereby allowing the end panels ia to be collapsed along the' dlagonal score lines 23 so that the main bodyoi the end flap Illa rests upon the bottom panel with the triangular wings 23 folded thereupon and with the end ilaps Ila and side panels Il folded sition and swing the portions I2 to positions adr jacent end walls Ita so that the container' cannot return to its collapsed `position. After the container has been packed, the extension panel il is folded inwardly along score line Il to a horizontal position and the cover panel i3 with the lateral extensions or tuck portions Isa, Ila is folded along the score line I4, the lateral extena,se1,oe7'

tively narrow securing strips carried bysaid side walls andfoldable outer portions, and mems firmly connecting said securing` strips with and in underlyins I lation to said wings.

2. The combination according to claim l including a cover formed on the upper edge of me of said side walls and cover extensions formed on sions, na, Isa stung into the poems formed between the wall portions 22, 22 of the end ilaps Ila and the end wall Ila, thus securing rigidity for the assembled container. It will be noted that the cut-out portions 2t are wide enough so that the naps llo, ila readily iit into the pockets even though the portions 2 I, 2l of the end naps are permanently secured to the end walls. Finally the cover is secured in place by tape or in any other suitable manner.

The invention has been described in dtail for the purpose of illustration, but it will be obvious that numerous modifications and variations may be resorted to without departing from the spirit of the invention. Y f

l. In a collapsible container formed from a single blank oi' sheet material, a bottom wall, side and end walls formed on said bottom wall and movable thereover when 'said container is in a folded condition, said end walls having foldable triangular-shaped wings on ltheir outer ledges, and wall ,flaps formed on the end edges of said'side walls rhaving creases therein substanthesideedgesofsaidcover adaptedtohein serted between said end wall ilaps and be said securing means. l

3. A collapsible container formed from a single blank oi' relatively heavy paperboard such as solid berboard or the like comprising a bottom wall, side and end walls formed on said bottom wall and ioldable thereover when said container is in -a. collapsed condition, said side walls having somewhat greater height than said end walls and each of said end walls including a pair of foidable triangular-shaped'winls deilned bythe side and upper edges thereof and a pair of fold lines at an angle of approximately from said bottom wall converging from the lower corners thereof, substantially rectangular end wall iiaps formed on the end edges of said side walls hav,

ing substantially the same height as said side walls, each of said ilaps having a fold line therein substantially parallel to said end edges and deiining a relatively narrow securing' strip carried by a side wall and a foldable outer portion, means iirmly rconnecting each ofY said securing strips in underlying relation toone 0i said wings adjacent its side edge, a cover formed on the upper edge of at least one of said side walls. and cover suon.
